UNASSIGNED: Tuberculous (TB) osteomyelitis of the foot is a rare entity, often leading to diagnostic challenges due to its atypical presentation and similarity to other foot pathologies.
UNASSIGNED: A 19-year-old male presented with persistent pain and discharge in the left foot for 9 months. Despite previous incision and drainage, the condition progressed. Clinical examination revealed a 1 × 1 cm swelling with indurated margins and a discharging sinus. Diagnostic imaging suggested osteomyelitis, confirmed as TB in nature through histopathological examination, revealing caseous necrosis and langerhans giant cells.
UNASSIGNED: This case illustrates the importance of considering TB osteomyelitis in differential diagnoses of chronic foot lesions and highlights the effectiveness of combined surgical and medical management.

Tuberculosis affecting the smaller bones of the foot is relatively infrequent. There is a paucity of data related to the tubercular involvement of cuboid and metatarsal bones. Diagnosis is challenging, especially in the absence of pulmonary involvement, a history of trauma, and contact with tuberculosis. We present a rare case of primary tuberculosis of the cuboid and fifth metatarsal without pulmonary involvement. The patient was started on anti-tubercular chemotherapy. A detailed literature search revealed that no such case with concomitant involvement of the cuboid and fifth metatarsal without pulmonary seeding has ever been reported.

UNASSIGNED: Isolated osteomyelitis of the cuboid is a rare entity with very few case reports worldwide. A variety of treatment methods are described for these lesions, both single-stage and two staged and ranges from simple curettage to bone grafting and arthrodesis.
UNASSIGNED: We present a series of two cases of chronic osteomyelitis in young adults due to puncture wound over the lateral foot. Both patients presented with purulent discharge from sinus over lateral foot. There was no involvement of adjoining bones in them. Culture yielded Staphylococcus aureus and Pseudomonas aeruginosa. Both patients were treated with adequate curetting, saucerization with cancellous bone grafting in one of the cases. Both wounds healed uneventfully with good ankle and hindfoot function.
UNASSIGNED: The cuboid is a rare site of chronic osteomyelitis due to punture wounds with foreign bodies, especially in rural population. With meticulous curettage and bone grafting, the infection can be eradicated reliably and usually with good residual function.

UNASSIGNED: To use the computed tomography (CT) attenuation of the foot and ankle bones for opportunistic screening for osteoporosis.
UNASSIGNED: Retrospective study of 163 consecutive patients from a tertiary care academic center who underwent CT scans of the foot or ankle and dual-energy X-ray absorptiometry (DXA) within 1 year of each other. Volumetric segmentation of each bone of the foot and ankle was done in 3D Slicer to obtain the mean CT attenuation. Pearson\'s correlations were used to correlate the CT attenuations with each other and with DXA measurements. Support vector machines (SVM) with various kernels and principal components analysis (PCA) were used to predict osteoporosis and osteopenia/osteoporosis in training/validation and test datasets.
UNASSIGNED: CT attenuation measurements at the talus, calcaneus, navicular, cuboid, and cuneiforms were correlated with each other and positively correlated with BMD T-scores at the L1-4 lumbar spine, hip, and femoral neck; however, there was no significant correlation with the L1-4 trabecular bone scores. A CT attenuation threshold of 143.2 Hounsfield units (HU) of the calcaneus was best for detection of osteoporosis in the training/validation dataset. SVMs with radial basis function (RBF) kernels were significantly better than the PCA model and the calcaneus for predicting osteoporosis in the test dataset.
UNASSIGNED: Opportunistic screening for osteoporosis is possible using the CT attenuation of the foot and ankle bones. SVMs with RBF using all bones is more accurate than the CT attenuation of the calcaneus.

The purpose of this case report is to raise awareness of an extremely rare cause of limping, in young children. Clinicians should have a high index of suspicion of a possible cuboid fracture when evaluating a young child who presents with limping.

UNASSIGNED: Tuberculosis (TB) affection of foot appears to be a rare clinical entity and accounts for <10% and 0.1-0.3% of osteoarticular and extrapulmonary TB, respectively. In TB foot, tarsal joints and calcaneum are more commonly affected followed by talus, distal end of first metatarsal, navicular, cuneiforms, and cuboid bones.
UNASSIGNED: A 24-year-old female presented with pain and swelling over dorsum of the left foot from the past 8 months. On examination, there was a diffuse round shaped, solitary swelling measuring about 3.5 cm × 2.5 cm (approx.) with its surface smooth, non-pulsatile, non-fluctuant, non-transilluminant, non-compressible, and non-reducible present over dorsum of the left foot. Radiographic investigations revealed osteolytic lesion over the base of 3rd, 4th, and 5th metatarsals, middle and lateral cuneiforms and cuboid bones along with soft tissue swelling and diffuse transient osteopenia. Under spinal anesthesia, trucut biopsy of the mass revealed paucibacillary type of TB in histopathological examination. The patient was provided with ATT drugs in the form of intensive phase drugs (HRZE) daily for 4 months and continuation phase drugs (HRE) daily for 10 months according to the weight of the patient. The patient was followed up with erythrocyte sedimentation rate and C-reactive protein every 2 months once. The patient achieved a normal range of movements in the midtarsal joints except for the painful terminal range of movements. The patient was still under our follow-up.
UNASSIGNED: The cuboid is the second most involved tarsal bone. The diagnosis is not always frankly evident, and a high index of suspicion has to be maintained. Surgical intervention should be limited to biopsy only as multidrug chemotherapy alone is sufficient to achieve complete healing.

This case report demonstrates a unique variant of a Chopart dislocation resulting in a plantar cuboid and navicular dislocation without concomitant fracture in a 48-year-old man. The mechanism of injury involved a low-energy plantarflexion moment from stepping off a small embankment. This report reviews the pertinent midfoot anatomy, discusses the proposed mechanism of injury, and demonstrates an effective method of treating these complex injuries with open reduction and internal fixation. Final results with 20 months of follow-up were excellent. This unusual midfoot dislocation is a complex injury that required open treatment for anatomic restoration. In complex Chopart dislocations, early open reduction should be strongly considered as the initial treatment to properly restore anatomy and function. Level of Evidence: Level V, expert opinion.

BACKGROUND: Clear recommendations about the optimal treatment of traumatic tarsal navicular fractures are still very debated in the literature, and this is due to several factors: navicular fractures are rare and often misdiagnosed injuries, they are frequently associated with other fractures or a dislocation of the midfoot, and the current knowledge is based on few papers mainly considering a limited number of cases and dealing with different therapeutic approaches. The treatment of navicular body fractures is controversial and burdened by a high incidence of complications; in particular, Sangeorzan type III comminuted fractures represent a real challenge for the orthopedic surgeon. An accurate preoperative planning, a scrupulous surgical technique aimed at restoring volume and bony anatomy, and the use of low-profile angular-stability plates can lead to optimal clinical and functional results, decreasing the chances of arthritic evolution of mid-foot joints.

UNASSIGNED: The purpose of this study was to evaluate clinical and radiological outcomes at skeletal maturity after a calcaneo-cuboid-cuneiform osteotomy (triple C osteotomy) for symptomatic flatfoot deformity compared with healthy young adult controls.
UNASSIGNED: Nineteen patients (30 feet) who undergone a triple C osteotomy for idiopathic symptomatic flatfeet from July 2006 to April 2013 were compared with 19 controls (38 feet). Radiographic measurements at preoperative examination, 1-year postoperative follow-up, and follow-up at skeletal maturity were evaluated. Functional outcomes were assessed by using the validated visual analog scale foot and ankle (VAS-FA) and the modified American Orthopaedic Foot and Ankle Surgery (AOFAS) score.
UNASSIGNED: In the triple C osteotomy group, 11 of 12 radiographic measurements were significantly improved at 1 year postoperatively and the last follow-up (p < 0.001). There was no recurrence at skeletal maturity (p > 0.05). There were no significant differences in nine of 12 radiographic measurements between the triple C osteotomy group at maturity and the control group (p > 0.05). Average VAS-FA and AOFAS scores were significantly improved at the time of skeletal maturity (p < 0.001).
UNASSIGNED: Surgical correction of symptomatic flatfoot deformity in childhood resulted in favorable outcomes after the triple C osteotomy. Deformity correction was also maintained during follow-up at skeletal maturity.
